False eyelash manufacturing process and processing device

Abstract

The invention relates to the technical field of false eyelash processing, and is particularly an improved false eyelash manufacturing process and processing device. The process comprises the following steps of: S 1 : obtaining an auxiliary film by a laser forming machine or a 3D printing film forming process; and S 2 : bending and shaping a tip part of an eyelash filament by a vacuum negative-pressure shaping method to obtain an eyelash filament with a curved tip part. According to the invention, a thread in an existing manufacturing process is replaced with the auxiliary film, so that compared with the thread, the auxiliary film has no greater elasticity, thus lowering operation requirements, making the manufacturing of false eyelashes more stable, and improving the production efficiency of false eyelashes.

We claim: 
     
       1. An improved false eyelash manufacturing process, wherein the process comprises the following steps of:
 S 1 : obtaining an auxiliary film by a laser forming machine or a 3D printing film forming process; 
 S 2 : bending and shaping a tip part of an eyelash filament by a vacuum negative-pressure shaping method to obtain an eyelash filament with a curved tip part; 
 S 3 : adhering the eyelash filament in the S 2  to an adhesive tape to form a half eyelash filament sheet, and then adhering two half eyelash filament sheets to form a whole eyelash filament sheet; 
 S 4 : adhering one side of the auxiliary film to one whole eyelash filament sheet, and adhering another whole eyelash filament sheet to another side of the auxiliary film to form a semi-finished product; 
 S 5 : gluing a position of the auxiliary film of the semi-finished product by a processing device; and 
 S 6 : cutting off a redundant part of the glued semi-finished product by a cutting tool, and taking a remaining part as a finished false eyelash product. 
 
     
     
       2. The improved false eyelash manufacturing process according to  claim 1 , wherein, in the S 1 , the step of obtaining the auxiliary film by the laser forming machine, comprises:
 S 11 : placing an auxiliary film raw material to be cut on a positioning table for fixing; 
 S 12 : utilizing a high-energy laser beam generated by a laser cutting machine in the laser forming machine, and cutting the auxiliary film raw material according to a preset cutting path; 
 S 13 : cutting the auxiliary film according to the preset cutting path by the laser cutting machine to obtain an auxiliary film in a required shape; and 
 S 14 : carrying out quality inspection on the obtained auxiliary film. 
 
     
     
       3. The improved false eyelash manufacturing process according to  claim 1 , wherein, in the S 1 , the step of obtaining the auxiliary film by the 3D printing film forming process, comprises:
 S 1   a : creating and importing a three-dimensional model of a required auxiliary film by computer software; 
 S 1   b : cutting the three-dimensional model of the auxiliary film into a thin layer with a standard thickness of the auxiliary film; and 
 S 1   c : presetting a high-temperature resistant release film on a working table of a 3D printer, and then starting up the 3D printer to print layer by layer according to a number of thin layers to obtain the required auxiliary film. 
 
     
     
       4. The improved false eyelash manufacturing process according to  claim 1 , wherein a shape of the auxiliary film comprises a strip, a block, a flake and a filament. 
     
     
       5. The improved false eyelash manufacturing process according to  claim 1 , wherein, in the S 2 , the step of bending and shaping the tip part of the eyelash filament by the vacuum negative-pressure shaping method, comprises:
 S 21 : placing the eyelash filament into a female die, wherein a bottom portion of the female die is provided with an air extraction port, and then pressing a male die above the female die to form a complete die; 
 S 22 : communicating an air extraction end of an air pump with the air extraction port at the bottom portion of the female die, and extracting air in an interior of the assembled die, so that the interior of the die is relatively vacuum, which enables the eyelash filament to be attached to a surface of the die; and 
 S 23 : physically bending and shaping the tip part of the eyelash filament by utilizing shapes of the female die and the male die in a relative vacuum environment.
